Update to text-1.2.4.0

1.2.4.0
* Add TH Lift instances for Data.Text.Text and Data.Text.Lazy.Text
  (gh-232)
* Update Haddock documentation to better reflect fusion eligibility;
  improve fusion rules for takeWhileEnd and length (gh-241, ghc-202)
* Optimise Data.Text.replicate from O(n) to O(log n) (gh-209)
* Support base-4.13.0.0

1.2.3.1
* Make decodeUtf8With fail explicitly for unsupported non-BMP
  replacement characters instead silent undefined behaviour (gh-213)
* Fix termination condition for file reads via Data.Text.IO operations
  (gh-223)
* A serious correctness issue affecting uses of take and drop with
  negative counts has been fixed (gh-227)
* A bug in the case-mapping functions resulting in unreasonably large
  allocations with large arguments has been fixed (gh-221)

1.2.3.0
* Spec compliance: toCaseFold now follows the Unicode 9.0 spec
  (updated from 8.0).
* Bug fix: the lazy takeWhileEnd function violated the lazy text
  invariant (gh-184).
* Bug fix: Fixed usage of size hints causing incorrect behavior
  (gh-197).
* New function: unsnoc (gh-173).
* Reduce memory overhead in encodeUTF8 (gh-194).
* Improve UTF-8 decoder error-recovery (gh-182).
* Minor documentation improvements (@since annotations, more examples,
  clarifications).

1.2.2.2
* The toTitle function now correctly handles letters that immediately
  follow punctuation. Before, "there's" would turn into
  "There'S". Now, it becomes "There's".
* The implementation of unstreaming is faster, resulting in operations
  such as map and intersperse speeding up by up to 30%, with smaller
  code generated.
* The optimised length comparison function is now more likely to be
  used after some rewrite rule tweaking.
* Bug fix: an off-by-one bug in takeEnd is fixed.
* Bug fix: a logic error in takeWord16 is fixed.

1.2.2.1
* The switch to integer-pure in 1.2.2.0 was apparently mistaken. The
  build flag has been renamed accordingly. Your army of diligent
  maintainers apologizes for the churn.
* Spec compliance: toCaseFold now follows the Unicode 8.0 spec
  (updated from 7.0)
* An STG lint error has been fixed
